Use of Non-GAAP Financial Measures

The Company reports its financial results in accordance with accounting principles generally accepted in the United States ("GAAP" or referred to herein as "reported"). However, management believes that certain non-GAAP financial measures provide management and other users with additional meaningful financial information that should be considered when assessing our ongoing performance. Our management regularly uses our supplemental non-GAAP financial measures internally to understand, manage and evaluate our business, establish operating budgets, set internal measurement targets and make operating decisions.

These non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with generally accepted accounting principles and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. The Company believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Harmonic's results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate Harmonic's results of operations in conjunction with the corresponding GAAP measures.

The Company believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures, provides useful information to investors and management regarding financial and business trends relating to its financial condition and its historical and projected results of operations. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to, the Company's reported results prepared in accordance with GAAP.

The non-GAAP measures presented here are: revenue, gross profit, operating expenses, income (loss) from operations, non-operating expenses and net income (loss) (including those amounts as a percentage of revenue), and net income (loss) per diluted share. The presentation of non-GAAP information is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP, and is not necessarily comparable to non-GAAP results published by other companies. A reconciliation of the historical non-GAAP financial measures discussed in this press release to the most directly comparable historical GAAP financial measures is included with the financial statements provided with this press release. The non-GAAP adjustments described below have historically been excluded from our GAAP financial measures.

Our non-GAAP financial measures reflect adjustments based on the following items, as well as the related income tax effects:

Cable Edge inventory charge - Harmonic from time to time incurs inventory impairment charges associated with material business shifts, such as the repositioning of our Cable Edge segment. We exclude these items, because we do not believe they are reflective of our ongoing long-term business and operating results.

Stock-based compensation - Although stock-based compensation is a key incentive offered to our employees, we continue to evaluate our business performance excluding stock-based compensation expenses. We believe that management is limited in its ability to project the impact stock-based compensation would have on our operating results. In addition, for comparability purposes, we believe it is useful to provide a non-GAAP financial measure that excludes stock-based compensation in order to better understand the long-term performance of our core business and to facilitate the comparison of our results to the results of our peer companies.

Amortization of intangibles - A portion of the purchase price of our acquisitions is generally allocated to intangible assets, and is subject to amortization. However, Harmonic does not acquire businesses on a predictable cycle. Additionally, the amount of an acquisition's purchase price allocated to intangible assets and the term of its related amortization can vary significantly and is unique to each acquisition. Therefore, we believe that the presentation of non-GAAP financial measures that adjust for the amortization of intangible assets provides investors and others with a consistent basis for comparison across accounting periods.

Restructuring and related charges - Harmonic from time to time incurs restructuring charges which primarily consist of employee severance, one-time termination benefits related to the reduction of its workforce, lease exit costs, and other costs. These charges are associated with material business shifts. We exclude these items because we do not believe they are reflective of our ongoing long-term business and operating results.

TVN acquisition- and integration- related costs - As a result of the Company's acquisition of Thomson Video Networks (TVN) in February 2016, the Company incurred acquisition-and integration-related expenses, including legal, accounting and other professional services as well as integration-related costs that are not expected to generate future benefits once the integration is fully consummated. We exclude these transaction and integration expenses because we believe these expenses have no direct correlation to the operation of our business, and because we believe that the non-GAAP financial measures excluding these costs provide meaningful supplemental information regarding our operational performance and liquidity. In addition, excluding these costs from the non-GAAP measures facilitates comparisons to our historical operating results and comparisons to peer company operating results.

Inventory fair value adjustment - Purchase accounting requires us to measure acquired inventory at fair value. The fair value of inventory reflects the acquired company's cost of manufacturing plus a portion of the expected profit margin. The non-GAAP adjustments to our cost of revenues exclude the expected profit margin component that is recorded under purchase accounting associated with our acquisitions. We believe the adjustments are useful to investors as an additional means to reflect cost of revenues and gross margin trends of our business.

Deferred revenue fair value adjustment - We define non-GAAP net revenues as net revenues excluding the impact of purchase accounting. In connection with our acquisitions, the acquired deferred revenue balances were required to be written down due to purchase accounting in accordance with GAAP. The impact on revenues related to purchase accounting as a result of these transactions, limits the comparability of revenues between periods. We do not expect revenues generated from new contracts to be similarly impacted by purchase accounting adjustments. Accordingly, we believe presenting non-GAAP net revenues to exclude the impact of purchase accounting adjustments aids in the comparability between periods and in assessing our overall operating performance.

Non-cash interest expense related to convertible notes - We record the accretion of the debt discount related to the equity component and amortization of issuance costs as non-cash interest expense. We believe that excluding these costs provides meaningful supplemental information regarding operational performance and liquidity, along with enhancing investors' ability to view the Company's results from management's perspective. In addition, we believe excluding these costs from the non-GAAP measures facilitates comparisons to our historical operating results and comparisons to peer company operating results.

Accounting impact related to warrant amortization - We issued a warrant to a customer, Comcast Corporation, in September 2016 pursuant to which Comcast may purchase up to 7.8 million shares of Harmonic common stock. Vesting of the warrant shares is subject to Comcast achieving certain milestones and purchase volume commitments, and therefore the accounting guidance requires that the value of the warrant be recorded as a reduction in the Company's net revenues. Until final vesting, changes in the fair value of the warrant share will be marked to market and any adjustment as such will also be recorded in revenue. The change in fair value together with vested warrant shares are amortized to revenue using a ratio of revenue recognized from the customer in the period compared to total revenue expected from the customer. We have excluded the effect of warrant amortization in our non-GAAP financial measures. Management believes it is useful to exclude the charge for the fair value of the warrant shares in order to better understand the effects of these items on our total revenues and gross margin.

Loss on impairment of long-term investments - We exclude the effect of any other-than-temporary impairment of a cost method investment in calculating our non-GAAP financial measures. We exclude these items because we do not believe they are reflective of our ongoing long-term business and operating results.

Avid litigation settlement and associated legal fees - In the third quarter of fiscal 2017, we settled the patent litigation with Avid Technology, Inc. by entering into a settlement and patent portfolio cross-license agreement with Avid. Under the agreement, we agreed to pay Avid a one-time non-recurring amount of $6 million in installments. $2.5 million was paid upfront in October 2017 and $1.5 million and $2.0 million will be paid in 2019 and 2020, respectively. Also, the Avid litigation costs of approximately $1.4 million and $0.7 million in the third and fourth fiscal quarter of 2017, respectively, were significantly higher compared to prior periods. We excluded these expenses from our non-GAAP results because we do not believe they are reflective of our ongoing long-term business and operating results.

Discrete tax items and tax effect of non-GAAP adjustments - The income tax effect of non-GAAP adjustments relates to the tax effect of the adjustments that we incorporate into non-GAAP financial measures in order to provide a more meaningful measure of non-GAAP net income.

The Company has also provided in this release the following non-GAAP financial measure:

Annual recurring revenue (ARR) - ARR is used to assess the trajectory of our OTT SaaS business. ARR means, as of a specified date, the contracted recurring revenue which includes both subscription and maintenance contracts (and excludes perpetual license, term license and service agreements) that are current and booked with a future start date. ARR should be viewed independently of revenue and any other GAAP measure.

(3) The Company has historically employed an aggregate allocation methodology based on total revenues to attribute professional services revenue and sales expenses between its Video and Cable Edge segments. Beginning in the fourth quarter of 2017, the Company has prospectively changed to a more precise attribution methodology as the activities of selling and supporting the CableOS solution have become increasingly distinct from those of Video solutions. The impact of making this change in the fourth quarter of 2017 compared to the Company's historical approach was a reduction in operating income of $2.4 million from the Video segment and a corresponding increase to operating income for the Cable Edge segment. The Company believes this updated internal allocation methodology will provide greater clarity regarding the operating metrics of the Video and Cable Edge business segments.
